BTLE Ad Filtering for Intent Capture in Multi-Lock Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In environments with multiple access controls, such as hotels, users face challenges in capturing their intent due to the numerous Bluetooth Low Energy (BTLE) advertisements from locks, leading to complexity in determining which lock to interact with.
Innovation Solution
A method involving a mobile device that filters BTLE advertisements based on credentials, received signal strength indicator (RSSI), proximity, and user intent, allowing for the determination of the intended access control through comparison and sorting of advertisements, and potentially using NFC tags or QR codes for precise identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lock is kept 'always on' sending periodic BTLE advertisements, then the user does not need to push a button to wake the lock, but in environments with multiple locks, each user receives advertisements from many locks complicating intent capture
Solution Approach 1:
The patent segments the advertisement data by filtering for specific credentials and organizing advertisements into groups based on spatial proximity and user context. This division of advertisements into manageable segments allows the system to handle multiple locks without overwhelming complexity.
Solution Approach 2:
The patent introduces an intermediary processing layer between the BTLE advertisements and the user intent determination. This intermediary filters and organizes advertisements based on credentials, proximity, and contextual factors, resolving the complexity of direct multi-lock advertisement handling.
2Adaptability or versatility
If multiple access controls send BTLE advertisements, then the system provides comprehensive coverage, but filtering and determining which lock the user intends to access becomes complex
Solution Approach 1:
The patent applies local quality by considering spatial proximity and contextual relevance for each advertisement individually. Advertisements from locks closer to the user or more relevant to the user's current context are prioritized, making intent determination easier while maintaining comprehensive coverage.
Solution Approach 2:
The patent changes parameters such as RSSI thresholds, credential matching criteria, and contextual factors to dynamically adjust advertisement filtering. This allows the system to maintain comprehensive coverage while simplifying intent detection by adjusting sensitivity parameters based on environmental conditions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach simplifies the interaction with access controls by filtering out irrelevant advertisements and determining user intent based on proximity and signal strength, enabling efficient and accurate selection of the intended lock without the need to manually wake up each lock.
Implementation Method 1
the access control system uses Bluetooth Low Energy (BTLE) to communicate with the mobile device
Implementation Method 2
comparing the filtered received advertisements; and determining a user intent to access a particular access control in response to the comparing and to a personal intent
Data Source
AI summary
A method of advertisement filtering including receiving advertisements from a multiple of access controls; filtering the received advertisements based on a credential on the mobile device; comparing the filtered received advertisements and determining a user intent to access a particular access control in response to the comparing and to a destination intent.
